In later years, hair-length is not that important.
Did they have long hair when young?
Also, is there a reason they wear their hair short, and how short is it?
When I say short, I mean short: above the ears.
In at least one of my posts on this thread, I had written the following:
"Hair communicates (though one must take into consideration a woman's entire appearance, considering how she would look with shorter hair as compared to wearing long hair up--while also taking into consideration whether she has long hair but is wearing it up because she is appears engaged in a certain activity, to accurately guess what her hair communicates)."
Note that in the above, I said one must consider hair-length not by itself, but in light of other aspects of woman's appearance.
Those other aspects include the way she is dressed, what she is doing at the time one observes her, whether she uses makeup, what kind of makeup, and how much, and one must observe other aspects of her hair: If long, has she treated it with chemicals, sprayed it with glue, puffed it out (big hair), or otherwise messed with it unnaturally?
For example: To me, if a woman I see in the street appears from her apparel to be working in an office that day, if her hair is long, I would expect a traditional woman to wear it up or pulled back--not free to wantonly fall over her shoulders or eyes.
